SOURCE: Monitor displays breifly then goes to blank screen

Well my Acer AL1711 finally gave up in as much as the screen flashed briefly at switch-on then went blank, regardless of brilliance setting so I decided to take it apart and try to fix it. The good news is that IT WAS NOT THE LAMPS that I feared in my earlier post and was easier than I had ever dreamed! First allow a good period of time for the internal components to discharge before starting. Remove the plastic clip at the base hinge to expose 4 screws - remove all four to release the stand. Then remove the 4 black cross head screws that appear to hold the back on, they do but there is more to do. Carefully tease the silver surround away from the case, best to start in the centre of each side and finish at the corners. There are many plastic clips to release before the surround comes away. Now remove the four cross head screws holding the pushbutton switch circuit board. The whole assembly can now be removed from the case and reveal a metal cover held by 2 SHORT (remember that!) SHORT! threaded machine screws. These once removed will allow the case to be slid away from the holding tabs located down the edges of the cover and removed. Now unplug the connectors from the board that has the mains input connector attached to it. You will see a heatsink with 4 electrolytic caps above it. Silly ACER designers, have placed the capacitors so that they get all the heat from the heatsink! Yes folks, the capacitors are above the heatsink when the monitor is in its normal operating position! So all the convected heat dries them out, nice. So the fault is due to a silly design error! Replace all 4 capacitors, two of them are 1000uF at 16V and the other two are 470uF at 16V, all radial types. Try and get capacitors with the highest operating temperature, at least 105 degree types and remember these are polarised, make sure you connect the capacitor + wire to + on the circuit board. You should have no problems with re-assembly but don't put the wrong screw where the short ones went or you are liable to see it come out of the screen LOL! Most important - - Don't forget the screw holding the earth tag to chassis. Good Luck, you will be amazed how much brighter the screen is now!

There is just no way you will be happy to hear it needs service or replacement under warranty.

Losing TV picture, screen goes blank,


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Screen going blank on system boot and on switch off/on


Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a fraction of seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Screen goes blank after 2 seconds


Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.

If it physicaly powers OFF, then you probably have a power issue.

Monitor displays breifly then goes to blank screen


The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
